Member Function Documentation

virtual bool esve::message::Active_State::active (   )  const [pure virtual, inherited]

Whether to pass messages to children. When active(), messages are relayed from parents to children. When active() == false, no messages are relayed. Implemented in esve::message::impl::Active_State, and esve::kernel::Caching_Node.

virtual void esve::message::Active_State::active (  bool   )  [pure virtual, inherited]

Whether to pass messages to children. When active(), messages are relayed from parents to children. When active() == false, no messages are relayed. Implemented in esve::message::impl::Active_State, and esve::kernel::Caching_Node.
